There's still gold in them thar rivers, and adventurers still cherish dreams of wealth. These days, though, sifting for gold is more a form of recreation than a business, and the tin pans have mostly been replaced by motorized machines called suction dredges. And the competing claims aren't over who has prospecting rights, but whether this form of mechanized gold hunting is causing irreparable harm to rivers in Northern California and the fish that swim in them. In 2011, Gov. Jerry Brown signed legislation that imposed a moratorium on the practice until 2016, by which time the state Department of Fish and Game was to adopt regulations that eliminated the potential for significant environmental damage and that set permit fees high enough to cover the state's costs.

BP's success at drawing oil from a leaking pipe has proved that official estimates of the size of the Gulf of Mexico spill have been too low. The company effectively admitted as much Thursday when it said that a tube inserted into the broken pipe connected to its blown-out well is collecting as much as 5,000 barrels of oil and 15 million cubic feet of gas a day, even as a live video feed shows large volumes continuing to billow into gulf waters....

Engineers hoping to contain oil gushing from the mangled pipe beneath the Gulf of Mexico appeared to make important headway Sunday, as robot submarines jammed a suction tube into the pipe in an attempt to coax the oil to a ship on the surface. Officials for the oil company BP said they could not estimate how much oil and gas was flowing through the tube, nor what percentage of the leak was being contained, until Monday or Tuesday at earliest. They originally said the plan might suck up as much as 75% of the leaking oil. Without the number of gallons retrieved, it remained unclear Sunday whether the nation's brightest minds would be capable of solving an engineering conundrum that is spewing 210,000 gallons of oil a day, and perhaps more, into the gulf waters from a canyon 5,000 feet below the sea. Although relatively little oil has washed up on land so far, scientists are growing worried about the effects of massive plumes of oil hovering below the surface in areas teeming with life, including plankton, turtles, dolphins and whales.

BP's efforts to slow the flow of oil into the Gulf of Mexico appeared to be working Monday as a mile-long suction tube captured about a fifth of the crude spouting from a broken pipe and transferred it to a waiting ship, company officials said. The suction operation is not stopping the flow of oil, but it is the first major success BP has achieved after weeks of failure in trying to check the oil gusher rising from nearly a mile below the gulf surface. "We're very encouraged by this," BP Chief Operating Officer Doug Suttles said Monday.

"Use it or lose it" goes for most things in life, including balance. Athletes use it to stick a landing, dodge a would-be tackler and score 9s on "Dancing With the Stars." When de-conditioned folks lose it, they feel shaky on a bike, walk stiffly and slowly, and risk falling and breaking their hip while vacuuming the floor. Fortunately, balance comes back when you work the quick-reaction core muscles that coordinate a body in motion, traditionally with the assistance of stability products such as wobble boards and Swiss balls.

So-called body-sculpting centers have become a sensation in the San Gabriel Valley, attracting Chinese American women eager to try an innovative approach to losing weight. No diets for them, thanks. They'd rather fight the war on flab with equipment that looks as if it came from a galaxy far, far away. The body-sculpting treatments, which are popular in Hong Kong and other East Asian cities and recall methods used in the U.S.
